This slide is thick skin so has all 5 possible layers. From deep to superficial the strata are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum and stratum corneum. The stratum basale has two types of cells in it; stem cells that produce replace lost cells and melanocytes which produce melanin. The stratum spinosum is the next layer has keratin producing cells (keratinocytes). The stratum granulosum looks granular due to a protein being made that helps bind the cells keratin. Thick skin will have a clear stratum lucidum between the granulosum and corneum. The cells of this layer are filled with a product called Eleidin . The last layer is the stratum corneum which is composed of dead cells that are constantly falling off.
